Honeywell has expanded its holistic Healthy Buildings Air Quality offering to help improve and measure commercial building indoor air quality with the introduction of Honeywell Electronic Air Cleaners (EACs) with UV Systems and a new line of indoor air quality (IAQ) sensors.

Honeywell EACs with UV help remove impurities from the air as well as provide filtration and disinfection, without significantly impeding air flow. The new IAQ sensors include Honeywell’s Particulate Matter Sensor PM2.5, Total Volatile Organic Compound (TVOC) Sensor and All-in-One IAQ Sensor.

“More people are paying attention to air quality and the importance of creating healthier environments in the spaces we use for work, school, entertainment and travel,” said Manish Sharma, vice president and chief technology officer, Honeywell Building Technologies. “Building owners are looking for ways to create safer, cleaner air to instill occupant confidence as well as attract future commercial tenants.”

Sharma continued: “We’re talking to hundreds of customers who are navigating these concerns right now and working with them to update their building systems to better protect occupants. It doesn’t always have to be a complicated process of ripping out old equipment and starting from scratch. It can be a straight-forward HVAC upgrade with modifications that address specific concerns and minimize potential side effects. Sensing technology is an important tool to identify opportunities for adjustments – only when you can measure particles can you properly control them. Adding a system like Honeywell’s can improve a building’s air quality by filtering particulates and reducing contaminants.”

Honeywell EACs use an electric charge to help remove solid and liquid impurities from the air without impeding air flow. The UV System emits ultraviolet light to damage the DNA structure of certain microbes at the cellular level and inactivate various viral, bacterial and fungal organisms – thus providing filtration and disinfection in one system.

Honeywell EACs with UV Systems can be installed inside a commercial HVAC system, without the need to remove old equipment and install a new system entirely. Importantly, Honeywell EACs with UV are well suited as a retrofit solution as a minimal pressure drop occurs, unlike the potential for high pressure drop when installing HEPA filters in existing systems. Honeywell EACs with UV tested for a MERV 14 rating by an independent third-party lab. Honeywell EACs can help save energy, while providing a better heat exchange and can pay for itself with the savings.

The new Honeywell IAQ sensors help building owners better determine a building’s environmental state and air quality status and allow them to take corrective actions through the building management system (BMS) without a need to rip and replace existing sensors. It is possible to add new sensors to existing temperature, humidity and CO2 sensors currently in place within the building or deploy new All-in-one IAQ sensors to cover multiple sensing requirements in one device.

Particulate Matter Sensor

Particulate matter (PM) sensors detect the concentration of PM within a space with a specific maximum diameter. The new Honeywell PM2.5 sensor detects particles with a diameter of 2.5 micrometers and smaller. The Honeywell PM2.5 sensors use an optical sensor based on laser scattering principles and feature innovative contamination resistance technology to perform highly accurate and reliable PM measurements. The sensor can provide long-term reliability and high-resolution particle size binning for the detection of environmental dust and other particles.

Total Volatile Organic Compounds (TVOC) Sensor

TVOC refers to the total concentration of multiple airborne VOCs present in the air at a specific time. Concentration of VOCs can be up to five times higher indoors than outdoors, demonstrating the need for sensing devices, filtration and ventilation strategies as part of the BMS.[3]

All-in-One IAQ Sensor

Honeywell All-in-One IAQ sensor is a single unit consisting of multi sensor suite including temperature, relative humidity, CO2, PM2.5 and TVOC, focusing on overall thermal comfort as well as air quality. The optimal range of temperature and humidity are known to reduce growth and spread of infectious bio-aerosols and thus pathogens.[4] The sensor can be used to cover multiple air quality factors to communicate healthy building status and enable the appropriate actions with the BMS.
